WP Super Cache is no problem.
I suspect you have server caching (such as xcache) which is caching the php files and not refreshing when they change. Contact your hosting company and ask them to disable any server caching.

I use APC, but I clear the APC cache after each update plugin.
Before I never had a problem with your plugin
